Build your very own little robots using the energy of solar power.
This great beginners' introduction to solar power technology requires no batteries, glue or screws for assembly - instead you build the kit with easy to connect pieces. Each of the four robotic designs come with active movements and a safe mechanical gearbox. The Robot features walking legs and moving wheels, the T-Rex and Rhino Beetle both have walking legs and opening jaws, while the Drill vehicle has a turning drill with moving wheels. Fun way to learn.
Nine year olds are clever little fellows and have lots of interests. Great presents for 9 year old boys are remote controlled cars or flying objects, science construction kits, anything that shoots, or outdoor gear. Magic is popular and anything involving pranks will appeal to that 9 year old sense of fun. Or get them a great book.
